This is just a starting point; more participation from everyone will make it more interesting. HaiChuan becomes even better with you in it. Prevention first, life above all. ----------------------------------------- Since April 2023, reporters from China Chemical Industry News have conducted in-depth on-site investigations into the current status of China’s independently developed high-temperature slurry-bed coal indirect liquefaction technology for oil production, as well as the options for upgrading and demonstrating this technology. The high-temperature slurry-bed indirect coal liquefaction technology for oil synthesis, developed by the team led by Li Yongwang from the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences and its transformation platform, Zhike Synthetic Oil Technology Co., Ltd., is one of the leading advanced technologies currently in use in China’s coal-to-oil sector. Yang Yong, Executive Vice President of Zhongke Synthetic Oil Technology Co., Ltd., explained that this technology has gone through various stages: laboratory testing from 1997 to 2000, pilot-scale tests from 2000 to 2008, industrial demonstration at a scale of 160,000 tons from 2009 to 2018, commercial demonstration at a scale of millions of tons from 2013 to 2018, and upgraded commercial demonstration at a scale of over 5 million tons since 2018. With this technology, the world’s largest single-unit coal indirect liquefaction facility with a capacity of 4 million tons per year was built in 2016; in 2017, a facility for producing fine chemicals from coal with a capacity of 1.2 million tons per year was established in Hangjin Banner, Inner Mongolia, and another coal indirect liquefaction facility with a capacity of 1 million tons per year was built in Lu’an, Shanxi. These three million-ton-scale coal indirect liquefaction plants have withstood the fluctuations in international oil prices, continued to operate steadily, and seen their process technologies continuously improve. Below is an introduction to the operations of Inner Mongolia Yitai and its development strategy. The 1.2 million tons per year fine chemicals demonstration project of Inner Mongolia Yitai Chemical Co., Ltd. uses 6 Spacecraft Long March coal gasification furnaces along with 3 multi-feed slurry gasification furnaces for gasification, and the high-temperature slurry-bed Fischer-Tropsch synthesis technology from China Science Academy for Fischer-Tropsch synthesis. Fischer-Tropsch synthesis products are further processed to produce a variety of fine chemicals. The entire process was completed in July 2017. In 2022, the operating load of the coal-based fine chemicals plant in Hangjin Banner, Inner Mongolia’s Yitai region reached 110%. Liu Wanzhou, chairman of Inner Mongolia Yitai Chemical Co., Ltd., said that for the company’s 1.2 million tons per year fine chemicals production facility, the comprehensive energy consumption per ton of product is 1.98 tons of standard coal; of this, the coal consumption per ton of product is 3.48 tons of standard coal, while the water consumption is 5.12 tons ； Energy conversion efficiency: 43.85% ； Zero wastewater discharge is achieved.
